Tough to remember the above if a wing drops abruptly at the stall, best to
have practiced a recovery technique so it's almost reflexive.<
Just a couple of thoughts regarding stall recovery. In my years of
instructing, few pilots recover from stall/wing drop with rudder even
though this is the correct method. It is a difficult habit to break, using
aileron in the stall recovery. Differential ailerons seems to mask the
improper aileron recovery so we generally get away with it.
I'm a big fan of practicing stalls but some aircraft are just not meant to
stall. I would put the IV in this category. Depending upon your
experience, some other Lancairs are not good platforms for learning or
brushing up on stall recoveries. Approaches to stalls are OK in any
aircraft including Lancairs and it is the recognition and recovery that we
are interested in. Approaches to stalls means that the pilot recognizes an
impending stall before it happens using the stall warner/AOA and effects a
coordinated recovery with minimum altitude loss and no secondary stall. The pre stall buffet on Lancairs does not give an adequate safe warning
even with stall strips based upon reports from reputable pilots. As I
understand it, stall strips on some Lancairs have made them spin resistant.
In the Lancair Network News it was reported that some experts felt the IV
was prone to a stall condition called laminar separation which is a violent
separation that occurs at the leading edge first and works rapidly aft. Not
exactly a pussy cat stall. Also keep in mind that stalls have to be practiced at a safe altitude by
FAR. Unfortunately stall recovery from a safe altitude looks completely
different as compared to a pattern altitude stall recovery. There are several eye opening reports from pilots stalling Lancairs in the
Lancair Network News. See Marv's LNN Archives.
